Performance in all directions

As part of the SIMATIC HMI family, the SCADA System SIMATIC WinCC Open Architecture (WinCC OA) is aimed at applications with a high requirement for customer-specific adaptations, large and/or complex applications, and projects that call for specific system requirements and functions. WinCC Open Architecture demonstrates its performance particularly well with networked and redundant high-end control systems. From field level to control station, from machine to company head office – consistent, high-performance communication is guaranteed. High availability, reliable information, fast interaction and user-friendliness are guaranteed in every situation. Application changes can be made without any process disruption. Profitability, efficiency and security are thus always harmoniously balanced. WinCC Open Architecture demonstrates its reliability in a multitude of business-critical applications. Ideas can be implemented in new applications quickly and easily. At the same time, the SCADA System can be developed independently in-house with its own product branding.

The specific features of this system enable WinCC Open Architecture to satisfy the highest requirements, particularly with regard to traffic solutions, building automation and public power supply (energy, water, oil and gas, etc.). Highlights SIMATIC WinCC Open Architecture: • Object orientation enables efficient engineering and flexible system expansion • Distributed systems up to 2048 servers • Scalable – from small single-user systems to distributed, redundant high-end systems with more than 10 million tags • Platform-independent and available for Windows, Linux and Solaris • Hot standby redundancy and Disaster Recovery System ensure the highest levels of system reliability and availability • Platform for customer-specific solutions • Extensive range of drivers and connection options: OPC, OPC UA, S7, Modbus, IEC 60870-5-101/104, DNP3, XML, TCP/IP

Profitability needs management The modular construction of the scalable process visualisation and control system means a future-proof investment for plant operators. All key functions are handled with separate, autonomous performance units, known as Managers. The Managers are processes that accomplish specific tasks for peripheral equipment connection, historical data storage, the user interface, etc.

Data point parameterization: • Data structures are organized intuitively in a tree structure • Individual parameterizations, such as report processing, archiving, addressing, are performed in clearly laid-out parameterization panels • Mass engineering is done in MS Excel. Import and export of configuration data is completely online • Data points can be generated and completely configured during operation. This means you can implement self-parameterizing objects • Integrated engineering with ETool – the standard parameterization tool enables quick, simple and costeffective engineering. Applications can be created at the touch of a button, with no need for S7 data training.

Connectivity Various drivers enable a connection to be made to the automation level. Key drivers available: Modbus Serial, Modbus Plus / RS485, RK512, TLS, Teleperm M, SSI Driver, IEC 60870-5-101, -104, DNP3, SINAUT, S7, Modbus TCP/IP, Ethernet/IP, OPC DA Client & Server, OPC A&E Client & Server, OPC UA Client & Server, SNMP, BACnet, API, Cerberus Depending on the performance requirement, WinCC Open Architecture can run on one or more computers – with distributed managers in the latter case. The client / server architecture enables the system to be adapted to suit requirements. Windows, Linux and Solaris operating systems are supported. Managers in SIMATIC WinCC Open Architecture: • Event Manager (EV) – constitutes the core of the system • Driver Manager (D) – manages the connection to field devices such as PLCs, RTUs, and DDCs • Data Manager (DB) – saves process changes in a highspeed database • Control Manager (CTRL) – takes care of event-controlled and multitasking-capable processing of programs/business logic • User Interface Manager (UI) – takes care of the graphic visualisation of process statuses

Other managers are available for specific functions such as redundancy, distributed systems, Web servers, reporting, simulation, COM, etc.

Data point concept The flexible data point concept is a key element in WinCC Open Architecture. External and internal variables, data structures of devices, user authorizations, and display of system images or alarms are all handled via data points. This ensures consistent processing and at the same time allows for flexible adaptation to specific issues. The number of data points is unlimited. 3

Efficient engineering

WinCC Open Architecture relies consistently on object orientation for process images and the database structure. This enables efficient and simple mass engineering and swift creation of projects with a number of parallel developments. Systematic and considered use of the objectoriented characteristics results in a change to the engineering process. In comparison with conventional methods, savings of up to 70% can often be made on engineering costs.

WinCC Open Architecture and S7 projects use simple standardizations with the help of ready-made libraries and component information from SIMATIC S7.

Engineering with WinCC Open Architecture: • Object-oriented databases and graphics • Importing and exporting application data • A high degree of standardization / normalization • Changes and enhancements possible during normal operation • Creation of a particular „smart“ engineering tool • Implementation of extremely complex, heterogeneous systems • Greater convenience for project engineers and users

The ETool engineering tool makes it possible to automatically integrate SIMATIC S7 projects into the SCADA system. This standard tool enables parameterization work to be completed quickly and easily. It offers the best possible support, and the system’s openness ultimately saves costs. This enables trouble-free data exchange, transferred from WinCC Open Architecture, to automatically create complete objects, contacts for all data point elements, and plant images in the SCADA project.

A system with a future

Distributed systems WinCC Open Architecture offers the option of “distributed systems” for large and/or geographically distributed applications. Distributed systems enable any number of stand-alone systems, 2 to 2048, to be linked via a network. Each subsystem can be configured either as a single-user or multiuser system, redundant or not, in each case. In this context, a subsystem means a server on which an Event Manager is running. Each system can process and display data from the other systems. The use of distributed systems (“Distributed Database”) ensures access to online values, alarms and histories for each system. Benefits of distributed systems in SIMATIC WinCC Open Architecture: • Flexibility and highly scalable • Improved performance due to parallel processing and load balancing • Fault tolerance and consequently enhanced availability of the entire system • Completely identical systems from parameterizing only once

Scalable structure WinCC Open Architecture can be used at various levels in a company’s automation pyramid, with HMI (Human Machine Interface) at the bottom of the pyramid, and PLCs, field buses, sensors and actors operating at field level. Directly above this level is SCADA where data from several local systems is collected and converted into regional or plant management information. Data at this level is often stored for lengthy periods in a relational database. The next and highest level is the central plant management level. This is where high-level process operation and data collection takes place. A high-performance system architecture of a modular construction forms the foundation of the entire system. This forms the basis of maximum system availability. This concept allows for one system at all levels. Multilingualism We offer a complete customer-specific solution. Despite standardized modules, WinCC Open Architecture is consistently designed to support use of multiple languages. Applications can be created in any language by simple parameterization, e.g. with Asian characters. The simultaneous use of different languages enables, for example, trouble-free access for remote maintenance. Development modifications or service work can be handled online from anywhere around the globe.

Benefits of WinCC Open Architecture: • Reliability provided by hot standby and Disaster Recovery System • Data security by means of duplicated data storage in two separate databases • Testing and parameterizing with no disruption to normal operation • Plant safety by avoiding operational disruption

The right choice for total security

Redundancy concept When short-term breakdowns result in substantial costs and problems, the highest levels of system availability and reliability are necessary. WinCC Open Architecture provides this reliability through its hot standby redundancy and Disaster Recovery System. If a unit develops a fault, continued operational management is guaranteed without any disruption. Effective provision is made for the loss of data and the problems associated with it. Hot standby redundancy This is a hardware-independent solution consisting of two interconnected server systems. Both servers are continuously in operation and are subject to the same functionrelated load. Only one server is active, while the second server is standby and reconciles run-time data with the primary unit. If a unit breaks down, an immediate switch occurs in which the previous standby server takes over operational management. Disaster Recovery System The Disaster Recovery System extends simple redundancy to a second redundant system, which can be switched to if a serious incident (e.g. fire or explosion in the building where the primary system is located) occurs. This additional local redundancy provides the highest possible level of reliability.

WinCC Open Architecture secured by Kerberos Kerberos provides WinCC Open Architecture with an authentication protocol, which ensures genuine and confidential communication between authorized parties. Basically, a secure server authenticates all participants in a system. Each person logs onto this server. The server verifies their identity and issues a key that participants use to recognize one another and, if necessary, to encrypt messages. This ensures integrity and complete, unmodified communication between sender and recipient. SIL3 IEC 61508 is the international standard for the functional safety of electrical, electronic and programmable electronic systems. SIL3 of the IEC 61508 imposes significant demands on responsibilities, processes, documentation and technologies for the development and approval of safety-relevant software. WinCC Open Architecture’s SIL3 certification means that the user saves time and consequently money, as the entire approval process for the control system is made considerably easier. Obligatory design and configuration requirements are available as a guideline together with the relevant technical expertise. Data archiving High-performance archiving of historical data enables complete traceability of system statuses. The system offers two different archiving solutions: archiving in Value Archives (internal database format) or archiving in an Oracle database. Oracle historicization is optimized for requirements in large and sophisticated projects. However, the proven and tested WinCC Open Architecture interfaces for archive maintenance are available. System resources can be used to include and remove, parameterize, and delete archives.

Video Framework Allows video management systems to be integrated into the SCADA system. Live images from cameras and images from network recorders or external video management systems can all be used as image sources. Cameras and streams can be included online using a simple drag-anddrop function. The image display components are used to display live video streams as full image, 2, 4 or 8 images per monitor as a 4CIF image and fault notifications can, depending on the event, be shown in video streams via encoders. Video sequences can be exported and made available as an AVI file for subsequent use. The combination of SCADA and video surveillance in one system is more cost-effective than using separate video interfaces, and additional maintenance and operational expenditure are reduced. It also reduces training time for operators.

Innovation creates trust

You will find WinCC Open Architecture in almost all industry sectors, from tunnel control systems to water and gas supply networks and even to CERN, the European Organization for Nuclear Research. It was here that WinCC Open Architecture held its ground during a 3-year evaluation against 100 rival competitors. The object-oriented concept and the handling of projects with data point volumes running into millions were ultimately the things that tipped the balance in its favor. All the project innovations and experiences relating to the CERN experiments were naturally fed into the product’s further development, so that the customer can now reap the benefits.

WinCC OA BACnet The full WinCC OA BACnet package combines building management technology and a top-level SCADA system in one package, providing direct access to automation levels. This is the ideal solution for large and/or distributed building and estates management. An integrated BACnet-compliant online/offline engineering solution for building management technology, including an object library, is available. The WinCC OA BACnet option allows the user to manage the building management technology in their usual environment, without the need to do without any of the additional SCADA functionality. WinCC OA BACnet manages the requirements of the latest building management technology and enables the implementation of future-proof and profitable concepts.

The industry-specific functions are proof of the development’s marketability. These functions were developed during the course of various projects and have now been incorporated as options within the product. GIS Viewer With this viewer, standardized maps of a Geographical Information System (GIS) can be fully integrated into the SCADA system. This makes it possible to show plant objects geographically on a map. This provides an attractive, enhanced plant overview that offers considerable benefits for the surveillance of large, distributed systems. Advanced Maintenance Suite (AMS) The maintenance management tool AMS is simple to parameterize and the functional scope includes efficient planning, management, execution and control of maintenance work and fault remedy. Events are evaluated by means of statistics and communicated by reports. 9

This architecture ensures scalability of the entire system across a wide area and a structure that suits the geographical conditions. Systems with millions of data points or up to 2048 geographically distributed server can be configured. Telemetry / telecontrol technology WinCC Open Architecture is often used in infrastructure projects. In these projects, telemetry and telecontrol technology play a key role. The SCADA system offers a variety of drivers that are specifically used in telecontrol technology:

Top level supervisory system

The entire architecture is divided, for example, into a central level, a communications server level and a field level. The central level consists of a redundant server pair, an Oracle cluster, various Web servers and servers for the IT infrastructure, and an optional ERP system (e.g. SAP). The redundant server pair maintains the connection for all communication servers and “services” all user interfaces. The Oracle cluster is used as a database server to store historical process values. Web servers are needed if Web clients are used. IT infrastructure servers can include file servers, mail servers, active directory or LDAP servers, etc. The integration of ERP data into the control system and for the reconciliation of process data feeding into an ERP system (e.g. SAP) can be requested as an option. The second level consists of the communication processors. These servers can be implemented as an individual system or as a redundant system, depending on availability requirements. Depending on the number of process values or operational concept requirements, a communication system services one or more plants with all its controllers. With very large plants, more than one communication system can be deployed for each plant. This layer can now be implemented locally (e.g. in a computer center) or distributed (directly in the plant), as required. The local installation option is implemented in cases where there is a particular need to ensure local operation if the central connection becomes interrupted. The field devices or the individual controllers in the plants constitute the lowest level.
